She began her career as a book critic for the magazines Commentary,[1]The New Republic, and The New Leader, where she wrote a book column and later, a movie column.[1] In 1986, she became an editor with the publishing house of Harcourt Brace Jovanovich. In 1997, after Tina Brown became editor of The New Yorker, Merkin became a film critic for the magazine. She also wrote extensively on books and became known for her frank forays into autobiography; her personal essays dealt with subjects ranging from her battle with depression, to her predilection for spanking,[2] to the unacknowledged complexities of growing up rich on Park Avenue. In 2005, she joined The New York Times Magazine as a contributing writer. She is the author of a novel, Enchantment (1984)[1] as well as two collections of essays, Dreaming of Hitler (1997)[3] and The Fame Lunches (2014).[4] and a memoir, This Close to Happy: A Reckoning With Depression (2017).[5]
